Remind students that in Chapter 4 they looked at the covalent bonding between oxygen and hydrogen, which creates the water molecule. Now students will look more closely at the details of the covalent ...

A substance that contains polar covalent bonds may not be overall polar. This is due to the shape of the molecule. Water molecules are polar molecules. Both of the bonds inside the molecule are ...

A shorter hydrogen bond, for instance, indicates stronger hydrogen bonding and a relatively weaker covalent bond. This was reflected, as expected, in lower spectroscopic frequencies for the H–F ...

Chemistry students the world over are familiar with covalent bonds and hydrogen bonds. Now a study has revealed a strange variety of bond that acts like a hybrid of the two. Its properties raise ...

These new bonds were only discovered in 2016, and are formed when the end of a lysine side-chain is linked to the end of a cysteine side-chain with an oxygen atom linking them together. The NOS ...

Researchers have found a new type of cross-link between amino acids in a protein (Nature 2021, DOI: 10.1038/s41586-021-03513-3). The intramolecular linkage is an N-O-S bridge formed by oxidizing ...

The higher an element's electronegativity, the stronger its ability to attract electrons and create a partial negative charge. In a chemical bond, the more electronegative atom gains extra electrons, ...

In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds. There are a total of 10 protons and 10 electrons, ... Alcohol has one O–H bond which is polar, but a large ...
